Has Anyone Actually Mowed Their Lawn This Summer?

By Jim Fellows, Garden-Review

Walk down any residential street in England this August and you'll see the same thing: lawns the colour of digestive biscuits, mowers gathering cobwebs in the shed, and more than a few gardeners quietly wondering whether their grass is dead or just sulking. It's a fair question. Between three separate heatwaves (37 consecutive heatwave days!) and, in some regions, the first hosepipe ban in half a century, 2026 has been brutal on British lawns. The good news is that most of that straw-coloured turf isn't dead at all – and now that the weather has finally turned, there's a right way and a wrong way to bring it back.

This summer, by the numbers

It helps to remember just how relentless this year has been. The UK broke its hottest-May record with 35.1°C at Kew Gardens in late May, then smashed the June record with 37.7°C at Lingwood in Norfolk – a heatwave severe enough for the Met Office to issue red extreme heat warnings on three consecutive days, only the second time that's happened nationally. A third heatwave in August pushed parts of England and Wales to 36–38°C under an amber warning. Little wonder the ground has given up.

By the time Wessex Water announced restrictions on 18 August, some parts of the South were 55 to 61 days without any measurable rain, according to the Met Office. Chief executive Ruth Jefferson called it the region's first hosepipe ban in 50 years, "the first since the famous drought of 1976," adding: "this isn't a decision we've made lightly and we're sorry for the inconvenience it will cause." Her colleague Will Willoughby, Director of Water Supply, pointed to a knock-on problem many gardeners won't have considered: "as the ground dries and moves, it causes the pipes below it to crack and leak," which is partly why a summer this dry strains the network as much as it strains your lawn.

Brown doesn't mean dead

If your lawn currently looks like toast, take heart. As the team at Hildreth's Home & Garden Centre put it, that colour is "a clever survival mechanism that allows the plant to conserve water until conditions improve" – the grass has effectively gone dormant, shutting down its leaves to protect the roots and crown below the soil. The RHS is unambiguous on this point too: "the grass will send up new leaves once it rains," and the underlying roots of most UK lawn grasses (which are used to our unpredictable climate) should still be very much alive.

Where you do need to worry is thin, patchy areas that were already under stress before the heat arrived, particularly anywhere with poor drainage, heavy foot traffic, or a lawn that was cut too short back in spring. Those spots may need reseeding rather than simply reviving, and autumn – not now – is the time to do it.

Will the rain actually be enough?

This is the question on everyone's mind, and the honest answer from the Met Office is: not on its own, and not straight away. Its meteorologists were careful in their most recent briefing to manage expectations, noting that "whether that rainfall can truly be described as 'meaningful' depends on location," since most of what's falling is scattered showers rather than the prolonged, soaking rain that actually replenishes soil moisture at depth. As they put it, "for areas that have seen little or no measurable rain for many weeks, this will certainly be a noticeable change, even if totals remain modest" – which is a polite way of saying your lawn will notice, but your local reservoir might not.

That matters for how you treat your own patch of grass, hosepipe ban or not. GreenThumb's lawn care specialists estimate that roughly 80% of UK lawns show visible signs of stress during a dry spell like this one, and that recovery genuinely takes time: around six weeks with rain alone, three to four weeks if you feed the lawn as growth resumes, and as little as seven to ten days if you combine feeding with a soil-wetting treatment to help water penetrate baked, hydrophobic ground. As they note, "it is easier to get water to penetrate a moist soil than it is to try and get it into a soil that is baked hard" – which is exactly the problem after nine weeks of drought.

If you're under a hosepipe ban

As of late August, Temporary Use Bans are in force across large parts of the country, including customers of Thames Water, South East Water, Anglian Water, Southern Water, Affinity Water, Cambridge Water, South West Water, Essex & Suffolk Water, Welsh Water and now Wessex Water. If that's you, the restrictions cover hosepipe use for the garden, but you can still legally use a watering can filled from a water butt or stored rainwater – and the RHS's advice makes this largely academic anyway, since established lawns shouldn't need hand-watering. Save any stored water for containers, veg beds and newly planted specimens instead, which will thank you for it far more than an established lawn will.

Don't reach for the mower just yet

The temptation, the moment you see a flush of green appear, is to get the mower out and tidy things up. Resist it for a week or two. New growth after drought stress is soft and shallow-rooted, and cutting it too early or too short simply re-stresses a lawn that's only just starting to recover. The RHS's general drought guidance applies just as much to the recovery phase: raise your cutting height, and don't take off more than a third of the leaf blade in any one cut.

Wait until you can see consistent, even green growth across the lawn – not just the odd hopeful shoot – before the first cut. When you do mow, keep the blades set high, go over it gently, and consider leaving the clippings in place for that first pass or two; they'll return some moisture and nutrients to soil that's had a hard summer. Dropping the blade height back down to your normal summer setting can wait until the lawn is clearly re-established, typically several weeks after rain returns in earnest.

What to watch for as the lawn wakes up

Recovery isn't always tidy. GreenThumb flags three things to expect once the rain does arrive: dormant weed seeds germinating right alongside your grass, red thread – a pink-tinged fungal disease that thrives on drought-stressed turf – and dry patch, where soil has become so water-repellent that rain simply runs off rather than soaking in. None of these are a sign you've done anything wrong; they're simply what a lawn does after nine or ten weeks under stress. A light autumn feed and, where needed, a wetting agent will deal with most of it.

Jim's top tips for bringing your lawn back to life

• Be patient before you're tempted to feed or weed. Let the lawn show two to three weeks of steady green regrowth before applying anything beyond a light autumn fertiliser.
• Raise the mower blades. A higher cut protects the crown of the plant and encourages deeper roots – the single biggest factor in surviving next year's dry spell better than this one.
• Don't scalp the first cut. Take off no more than a third of the blade length, and only once growth is even across the whole lawn.
• Check your local restrictions. Search your postcode with your water company before using a hose for anything in the garden – and remember a watering can from a water butt is usually fine even under a ban.
• Save stored water for what actually needs it. Pots, hanging baskets and anything planted this year should take priority over an established lawn.
• Plan to reseed bare patches in autumn. September is prime lawn renovation season in the UK – cooler air, warm soil and (usually) reliable rain make it far more effective than trying to fix things now.
• Watch for red thread and dry patch. Both are common after a drought this severe and are treatable rather than fatal – a light feed and, if water is pooling or running off, a soil wetting agent will help.
• Get your mower ready while you wait. Sharpen the blades and give it a service now, so you're not caught out the moment the lawn is ready to cut.

So: has anyone actually mowed their lawn this summer? Not much, and for good reason – and if you haven't, you've probably done your lawn a favour. Give it a few more weeks of the right kind of patience, and by the time the clocks go back, most gardens should look like gardens again.
